FIG. 1 is a perspective view of the tire tread of my design;

FIG. 2 is a front elevation view of the tire tread of my design;

FIG. 3 is a side elevation view of the tire tread of my design;

FIG. 4 is a side elevation view of the tire tread of my design, taken from the opposite side of that shown in FIG. 3; and,

FIG. 5 is an enlarged, partial view of the tire tread of FIG. 1, as indicated by the break lines.

In the drawings, the broken lines depict environmental subject matter that forms no part of the claimed design. The dash-dot-dot-dash line defines the peripheral boundary between the claimed tire tread and the unclaimed sidewall. The tread pattern repeats uniformly throughout the circumference of the tire.
